2、导入相关的配置文件

3、关键配置
(1) web.xml:配置过滤器,监听器,核心控制器,
<filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 确定Spring配置文件的位置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 在Web容器启动的时候初始化Spring容器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 指定SpringMVC的配置文件路径 --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc-servlet.xml</param-value> </init-param> <!-- 加载servlet优先级,数值越小优先级越高 --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
(2)springmvc.xml:
1.指定需要扫描的控制器
2.配置视图解析器
3.文件上传解析器
4.json解析器
<?xml version="1.0" encoding="UTF-8"?>

</bean>
</beans>
(3)applicationContext.xml:
开启包扫描
配置数据源,
整合mybatis,
扫描Service
Dao(采用注解方式实现依赖),
配置事务管理器
事务的策略
事务范围
<?xml version="1.0" encoding="UTF-8"?>

<aop:config>
<aop:advisor advice-ref="txAdvice"
pointcut="execution(* com.qf.service..*.*(..))" />
</aop:config>
</beans>
(4)spring整合mybatis
导入mybatis-spring-1.2.0.jar
mybatis-config.xml 配置别名
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <typeAliases> <package name="com.qf.entity"/> </typeAliases> </configuration>
0.数据库

public class Account {
private Integer id;
private String name;
private Double balance;
private String inName;
private String outName;
private Double money;
}
package com.qf.entity;
import java.util.List;
public class Page {
/**
* 当前页
*/
private Integer currentPage = 1;
/**
* 每页显示的行数
*/
private Integer pageSize = 3;
/**
* 总页数
*/
private Integer totalPage;
/**
* 总条数
*/
private Integer totalCount;
/**
* 展示数据
*/
private List<?> list;
/**
* 查询路径
*/
private String url;
public void setTotalCount(Integer totalCount) {
this.totalCount = totalCount;
this.totalPage = totalCount % pageSize == 0 ? totalCount / pageSize : (totalCount/ pageSize) + 1;
}
}
4.con.qf.dao包中创建接口

public T getById(Integer id);
public int getCount();
public List<T> getList(Integer startIndex,Integer size);
}
package com.qf.dao;
import com.qf.entity.User;
public interface IUserDao extends IBaseDao<User>{
}
package com.qf.dao;
import com.qf.entity.Account;
public interface IAccountDao extends IBaseDao<Account> {
/**
* 进账
* @param name 用户名
* @param moeny 金额
*/
public void in(String name,Double moeny);
/**

public BaseDaoImpl() {
ParameterizedType parameterizedType = (ParameterizedType) this.getClass().getGenericSuperclass();
Type[] actualTypeArguments = parameterizedType.getActualTypeArguments();
entity = (Class<T>) actualTypeArguments[0];
}
@Override
public int add(T t) {
return getSqlSession().insert("com.qf.dao.I" + entity.getSimpleName() + "Dao.add", t);
